Problem: Part AWhich of the following are correct for zero-order reactions? Check all that apply.a. The concentration of the reactants changes nonlinearly.b. The higher concentration of reactants will not speed up the reaction.c. The rate of reaction does not equal the rate constant.d. The units for the rate constant and the rate of reaction are the same.e. A zero-order reaction slows down as the reaction proceedsPart BIn the hydrogenation of ethylene using a nickel catalyst, the initial concentration of ethylene is 1.70 mol⋅L−1 and its rate constant (k) is 0.0014 mol⋅L−1⋅s−1 . Determine the rate of reaction if it follows a zero-order reaction mechanism.

Part A

Which of the following are correct for zero-order reactions? Check all that apply.

a. The concentration of the reactants changes nonlinearly.

b. The higher concentration of reactants will not speed up the reaction.

c. The rate of reaction does not equal the rate constant.

d. The units for the rate constant and the rate of reaction are the same.

e. A zero-order reaction slows down as the reaction proceeds


Part B

In the hydrogenation of ethylene using a nickel catalyst, the initial concentration of ethylene is 1.70 mol⋅L−1 and its rate constant (k) is 0.0014 mol⋅L−1⋅s−1 . Determine the rate of reaction if it follows a zero-order reaction mechanism.
